Data
Staff of USGS Science Centers in Region 7: Upper Colorado Basin collect a wide variety of natural resource data types including spatial, geologic, hydrologic, and biologic. Data included in USGS-series publications that are not publicly available in USGS databases are published in Data Releases. Short descriptions and links to Data Releases produced by Region 7 Science Centers are shown below.

Spatial social value distributions for multiple user groups in a coastal national park Spatial social value distributions for multiple user groups in a coastal national park
Public participation geographic information systems (PPGIS) is increasingly used in coastal settings to inform natural resource management and spatial planning. Social Values for Ecosystem Services (SolVES), a PPGIS tool that systematizes the mapping and modeling of social values and cultural ecosystem services, is promising for use in coastal settings but has seen relatively limited...
Wetland burned area extent derived from Sentinel-2 across the southeastern U.S. (2016-2019) Wetland burned area extent derived from Sentinel-2 across the southeastern U.S. (2016-2019)
Wildfires and prescribed fires are frequent but under-mapped across wetlands of the southeastern United States . High annual precipitation supports rapid post-fire recovery of wetland vegetation, while associated cloud cover limits clear-sky observations. In addition, the low burn severity of prescribed fires and spectral confusion between fluctuating water levels and burned areas have...
North American tree-ring fire-scar site descriptions North American tree-ring fire-scar site descriptions
Fire size and severity continue to increase across large parts of North America, driven by a combination of climate change and effects of human land use. Instrumental records are too short to fully understand patterns, trends, and drivers of fire that are necessary to model future fire. Tree-ring fire scars provide centuries-long records of fire regimes, including fire frequency, season...
Global biomes for the Last Interglacial period (127-119 ka) simulated by BIOME4 using CESM2-CISM2 coupled climate–ice sheet model data Global biomes for the Last Interglacial period (127-119 ka) simulated by BIOME4 using CESM2-CISM2 coupled climate–ice sheet model data
This data release contains: 1) the BIOME4-simulated biome data used to create Sommers et al. (2021) Figures 2, 6, S6, and S7; 2) the CESM2-CISM2 calendar-adjusted temperature data used to create Sommers et al. (2021) Figures 2, 7, S2-S5, and S8-S11; and 3) land, ice, and ocean mask data and continent and ice sheet outline files. Additional CESM2-CISM2 simulation data described in Sommers...
Biomes simulated by BIOME4 using CESM2 lig127k, midHolocene, and piControl climate data on a global 0.5-degree grid Biomes simulated by BIOME4 using CESM2 lig127k, midHolocene, and piControl climate data on a global 0.5-degree grid
This data set consists of simulated biomes for the last interglacial (127 ka), middle Holocene (6 ka), and preindustrial (1850 CE) time periods displayed in Figure 14 of Otto-Bliesner et al. (2020). Biomes were simulated with BIOME4 (ver. 4.2, https://pmip2.lsce.ipsl.fr/synth/biome4.shtml; Kaplan et al., 2003), an equilibrium vegetation model, using CESM2 (ver. 2.1.0) simulated climate...
Adult male horse data from Conger and Frisco Herd Management Areas, Utah, USA, between 2017 and 2020 Adult male horse data from Conger and Frisco Herd Management Areas, Utah, USA, between 2017 and 2020
We studied the effect of castrating a proportion of the adult males in a feral horse herd to examine any effect on behavior and social associations, particularly in terms of association with mares (i.e., maintenance of a harem group). We conducted this study between 2017 and 2020 at two Herd Management Areas (HMAs) in western Utah, USA: Conger and Frisco. We conducted demographic...
Propensity of cold air drainage index and related variables Propensity of cold air drainage index and related variables
Cold air drainage down slopes may form cold air pools in valleys and surface depressions. These cold air pools can significantly affect ecosystem processes, agricultural crops, and air quality. Rupp et al. (2021, Theoretical and Applied Climatology, https://doi.org/10.1007/s00704-021-03712-y) proposed a propensity of cold air drainage index to represent the likelihood of occurrence of...
Database of invasive annual grass spatial products for the western United States January 2010 to February 2021 Database of invasive annual grass spatial products for the western United States January 2010 to February 2021
Invasive annual grasses (IAGs) present a persistent challenge for the ecological management of rangelands, particularly the imperiled sagebrush biome in western North America. Cheatgrass (Bromus tectorum), medusahead (Taeniatherum caput-medusae), and Ventenata spp. are spreading across sagebrush rangelands and already occupy at least 200,000 kilometers squared (km sq.) of the...
The Landsat Burned Area products for the conterminous United States (ver. 3.0, March 2022) The Landsat Burned Area products for the conterminous United States (ver. 3.0, March 2022)
The U.S. Geological Survey (USGS) has developed and implemented an algorithm that identifies burned areas in temporally-dense time series of Landsat Analysis Ready Data (ARD) scenes to produce the Landsat Burned Area Products. The algorithm makes use of predictors derived from individual ARD Landsat scenes, lagged reference conditions, and change metrics between the scene and reference...
Data inputs and outputs for simulations of species distributions in response to future fire size and climate change in the boreal-temperate ecotone of northeastern China Data inputs and outputs for simulations of species distributions in response to future fire size and climate change in the boreal-temperate ecotone of northeastern China
This data release provides inputs needed to run the LANDIS PRO forest landscape model and the LINKAGES 3.0 ecosystem process model for the temperate-boreal ecotone Great Xing'n Mountains of northeastern China, and simulation results that underlie figures and analysis in the accompanying publication. The study compared the impacts of small and large fires on vegetation dynamics. The data...
Spectral reflectance measurements of radiometric calibration panels for UAS image calibration Spectral reflectance measurements of radiometric calibration panels for UAS image calibration
Calibration panels are used as reference materials with known reflectance characteristics to convert remote sensing image pixel values to scientific units such as reflectance. At the time of purchase, the panel vendor typically provides the customer with reflectance data for the panel. The vendor-provided spectral data as a reference for each panel’s reflectance values at the time of...
Winter herbaceous utilization by elk and bison in the Great Sand Dunes National Park ecosystem of the San Luis Valley, Colorado, 2006 to 2008 Winter herbaceous utilization by elk and bison in the Great Sand Dunes National Park ecosystem of the San Luis Valley, Colorado, 2006 to 2008
These data represent 2 years of plant clipping data in areas with elk plus bison and areas of elk only in the San Luis Valley of Colorado, USA from 2006-2008. Clipping plots were measured (clipped) in meadow sites, herbaceous riparian sites, and willow communities. We clipped 1/4 m2 (meter-squared) rings inside and outside of 1-m2 grazing cages, as well as within large ungulate...
